INTRODUCTION This guide shows the steps necessary to replace the O-Ring on the Nerf N-Strike Maverick. First, you should consult steps 1 through 4 of the Nerf N-Strike Maverick Teardown guide. Make sure you have a replacement O-Ring on hand.
Another Phillips screw hides beneath the cocking mechanism thing. Remove that one as well.
The cocking mechanism's quite simple. A metal lever pulls back on the air plunger and compresses the large spring. Another small spring returns the slider back into its original position once it's done doing the dirty business..
Step 4
And just like that, the gun comes apart.
Visible in the top left corner is the large spring and air plunger.
I later opened the gun again and put a folded piece of paper in this area. It gave the gun a bit more "punch" when sending darts on their merry way.
The trigger is held in place by a sole Phillips screw. It also has a small spring for that authentic handgun "springy" feeling...
Step 8
The trigger's spring also attaches via a Phillips screw. A couple of twists with the screwdriver and it comes right out.
The fancy rotator for the barrel is next. I assume that were the gun to break, this would be the part that fails. It's the most complex part of the gun.
Follow steps 1 through 4 of the Nerf N-Strike Maverick Teardown guide.

Step 13 — Locate the Gasket
Locate the air plunger in the upper left hand corner of the opened nerf gun. Push back on the spring and carefully pull the plunger toward you to remove it.
Once you have the air plunger removed, locate the O-Ring by pulling the two pieces of the air plunger apart.
